Why would the 'low oil' warning light come on in your 2002 Impala after 2 quarts of oil were added just 4 weeks ago?

Answer 1

on most vehicles, this would indicate a leak, whether internal or external. First thing is to watch your exhaust smoke for white color, this indicates either blow by or a seal problem in most cases. I have the same problem with my 2002 impala and it is not likely that blowby is causing the oil consuption. The was a defect in the intake of some of the impala's equppied with 3.8 and the 3.4 liter engine. Go to your local dealer or auto parts store and purchase a bottle of black light reactive die that you puor into the oil. Afterr a week of normal driving shine a black light on the engine focusing more on the rear of the engine just below the intake and I almost guarantee that you will find the leak.
